[0002] The foregoing applications, and all documents cited therein or during their prosecution ("appln cited documents") and all documents cited or referenced in the appln cited documents, and all documents cited or referenced herein ("herein cited documents"), and all documents cited or referenced in herein cited documents, together with any manufacturer's instructions, descriptions, product specifications, and product sheets for any products mentioned herein or in any document incorporated by reference herein, are hereby incorporated herein by reference, and may be employed in the practice of the invention. More specifically, all referenced documents are incorporated by reference to the same extent as if each individual document was specifically and individually indicated to be incorporated by reference.
FIELD OF THE INVENTION id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3"
[0003] The invention relates to methods for treating COVID-19 by targeting the inflammasome/caspasel/pyroptosis axis as a key inflammatory pathway.
BACKGROUND OF THE INVENTION id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4"
[0004] Beginning in December 2019, a novel coronavirus first detected in Wuhan, China, and designated SARS-C0V-2, has caused an international outbreak of respiratory illness termed Covid- 19. Since the initial detection of the virus, millions of cases of Covid-19 have been confirmed worldwide, with the first reported cases in the US occurring on January 19, 2020 (Holshue et al.
N Engl J Med. 2020;382(10): 929-936). The full spectrum of Covid-19 ranges from mild, self- limiting respiratory tract illness to severe progressive pneumonia, multiorgan failure, and death (Chen et al. Lancet. 2020; 395(10223): 507-513). Initial reports, first from China and then from Italy, stressed high mortality rates, ranging from 2.3% overall to as high as 15% in those aged 80 years and older (Grasselli G, A. Pesenti A, and M. Cecconi M. Critical Care Utilization for the COVID-19 Outbreak in Lombardy, Italy: Early Experience and Forecast During an Emergency Response. JAMA. 2020). However, this is likely an overestimate since the prevalence of 1 asymptomatic carriers is as yet unknown. What is increasingly clear, though, is that individuals at highest risk are those over 65 years with concomitant chronic conditions with an inflammatory profile such as diabetes, pre-diabetes, elevated BMI, liver disease, and chronic renal impairment. id="p-5" id="p-5" id="p-5" id="p-5" id="p-5" id="p-5" id="p-5" id="p-5" id="p-5" id="p-5" id="p-5"
[0005] After the emergence of severe acute respiratory syndrome (SARS) in 2003, screening of approved drugs identified lopinavir, a human immunodeficiency virus (HIV) type 1 aspartate protease inhibitor, as having in vitro inhibitory activity against SARS-CoV, the virus that causes SARS in humans (Chen et al. J Clin Virol. 2004;31(l): 69-75; Chu et al. Thorax. 2004;59(3): 252- 256; Wu et al. Proc Natl Acad Sci USA. 2004;101(27): 10012-10017). Ritonavir is combined with lopinavir to increase its plasma half-life through the inhibition of cytochrome P450. An open- label study published in 2004 suggested, by comparison with a historical control group that received only ribavirin, that the addition of lopinavir-ritonavir (400 mg and 100 mg, respectively) to ribavirin reduced the risk of adverse clinical outcomes (acute respiratory distress syndrome or death) as well as viral load among patients with SARS (Chu et al. Thorax. 2004;59(3): 252-256).
However, the lack of randomization and the concomitant use of glucocorticoids and ribavirin in that study made the effect of lopinavir-ritonavir difficult to assess. id="p-6" id="p-6" id="p-6" id="p-6" id="p-6" id="p-6" id="p-6" id="p-6" id="p-6" id="p-6" id="p-6"
[0006] Recently, the combined effect of lopinavir-ritonavir in the treatment of SARS-C0V-2 was tested in a randomized study involving 200 patients in China. Unfortunately, there was no improvement in clinical symptoms, mortality, or viral loads in the lopinavir-ritanovir group compared to standard of care alone (Chu et al. Thorax. 2004;59(3): 252-256).
Hydroxychloroquine, an anti-malarial agent, combined with azithromycin, an anti-bacterial agent, were recently used in 22 patients with SARS-C0Vid-2 infection in France. Viral loads appeared to diminish faster in the treated patients than in the 2 control patients, but no conclusions can be drawn from such small numbers and anyway no mention was made of its impact on clinical symptoms. id="p-7" id="p-7" id="p-7" id="p-7" id="p-7" id="p-7" id="p-7" id="p-7" id="p-7" id="p-7" id="p-7"
[0007] The role of the inflammasome/caspasel/pyroptosis axis as a key inflammatory pathway in the context of coronavirus infections and beyond is well known in the art. (files labelled C0V- 01 - C0V-O6). id="p-8" id="p-8" id="p-8" id="p-8" id="p-8" id="p-8" id="p-8" id="p-8" id="p-8" id="p-8" id="p-8"
[0008] Yue et al. (Cell Death and Disease (2018) 9:904) found that Receptor Interacting Protein 3 (Rip3)-mediated oligomerization of SARS 3a (the largest of the SARS-CoV accessory protein open reading frames) causes necrotic cell death, lysosomal damage, and caspase-1 activation—all likely contributing to the clinical manifestations of SARS-CoV infection. Yue et 2 al. also found that SARS 3a activates caspase-1 either directly or via an enhanced potassium efflux, which triggers NOD-, LRR- and pyrin domain-containing protein 3 (NLRP3) inflammasome assembly. id="p-9" id="p-9" id="p-9" id="p-9" id="p-9" id="p-9" id="p-9" id="p-9" id="p-9" id="p-9" id="p-9"
[0009] Shi et al. (Cell Death Discovery (2019) 5:101) identified several mechanisms by which a SARS-CoV open reading frame (ORF) activates intracellular stress pathways and targets the innate immune response by activating NLRP3 inflammasomes. id="p-10" id="p-10" id="p-10" id="p-10" id="p-10" id="p-10" id="p-10" id="p-10" id="p-10" id="p-10" id="p-10"
[0010] Zalinger et al. (J. Neurovirol. (2017) 23:845-854) used murine coronavirus, mouse hepatitis virus (MHV), infection of the central nervous system and liver to assess of the role of the inflammasome and its related cytokines on pathogenesis and host defense during viral infection.
Their data suggest that inflammasome signaling is largely protective during murine coronavirus infection, in large part due to the pro-inflammatory effects of IL-18. id="p-11" id="p-11" id="p-11" id="p-11" id="p-11" id="p-11" id="p-11" id="p-11" id="p-11" id="p-11" id="p-11"
[0011] Jiang et al. (Viruses 2019, 11, 39; doi:10.3390/vl 1010039) found that MERS-CoV infection induced pyroptosis and over-activation of complement in human macrophages. Jiang et al.'s data indicate that MERS-CoV infection induces overactivation of complement, which may contribute to pyroptosis and inflammation. Pyroptosis and inflammation were suppressed by inhibiting C5aRl. id="p-12" id="p-12" id="p-12" id="p-12" id="p-12" id="p-12" id="p-12" id="p-12" id="p-12" id="p-12" id="p-12"
[0012] Kesavardhana et al. (Annu. Rev. Immunol. 2020. 38:567-95) reviewed mechanisms governing caspase activation and programmed cell death with special emphasis on the recent progress in caspase cross talk and caspase-driven gasdermin D (GSDMD)-induced pyroptosis. id="p-13" id="p-13" id="p-13" id="p-13" id="p-13" id="p-13" id="p-13" id="p-13" id="p-13" id="p-13" id="p-13"
[0013] Guo et al. (PL0S Pathog 2015 11(9): 61005155. doi:10.1371/joumal. ppat.1005155) demonstrate that the reactive oxygen species (ROS)/nucleotide-binding domain-like receptor protein 3 (NLRP3)/interleukin-1p (IL-ip) axis institutes an essential signaling pathway, which is over activated and directly causes the severe liver disease during viral infection, which sheds light on development of efficient treatments for human viral fulminant hepatitis and other severe inflammatory diseases. id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14"
[0014] The relevance of the inflammasome/caspasel/pyroptosis axis specifically in COVID- 19 is also known in the art. id="p-15" id="p-15" id="p-15" id="p-15" id="p-15" id="p-15" id="p-15" id="p-15" id="p-15" id="p-15" id="p-15"
[0015] Parisi and Leosco (Precision medicine in COVID-19: IL-1p a potential target, JACC: Basic to Translational Science (2020)) speculated about i) the role of NLRP3 in the clinical variability of COVID-19; ii) the potential therapeutic effect in COVID-19 of IL-1p inhibition 3 (canakinumab, anakinra), and iii) the role of visceral adipose tissue in the inflammatory response to SARS-CoV-2 infection. id="p-16" id="p-16" id="p-16" id="p-16" id="p-16" id="p-16" id="p-16" id="p-16" id="p-16" id="p-16" id="p-16"
[0016] Conti et al. (Journal of biological regulators and homeostatic agents Volume 32 Issue 2 2020) speculated about anti-inflammatory strategies, specifically the induction of pro- inflammatory cytokines (IL-1 and IL-6) and lung inflammation by Coronavirus-19 (COVID-19 or SARS-CoV-2). id="p-17" id="p-17" id="p-17" id="p-17" id="p-17" id="p-17" id="p-17" id="p-17" id="p-17" id="p-17" id="p-17"
[0017] Yang (Cell Pyroptosis, a Potential Pathogenic Mechanism of 2019-nCoV Infection (January 29, 2020). Available at SSRN: https://ssrn.com/abstract=3527420 or http://dx.doi.org/10.2139/ssrn.3527420) discussed the relationship between 2019-nCoV infection and cell pyroptosis. Yang's hypothesis of the relationship between 2019-nCoV and cell pyroptosis is presented in FIG. 1. id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18"
[0018] Deftereos et al. (Hellenic Journal of Cardiology, 2020, https://doi.Org/10.1016/j.hjc.2020.03.002) asked whether colchicine, administered in a relatively low dose, could potentially have an effect on the patients' clinical course by limiting the myocardial necrosis and pneumonia development in the context of CO VID-19. If present, this effect would be attributed to its potential to inhibit inflammasome and (less probably) to the process of SARS- C0V-2 endocytosis in myocardial and endothelial respiratory cells. id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19"
[0019] There is a need for effective therapeutic agents to treat coronavirus infections, in particular SARS-CoV-2. id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20"

DETAILED DESCRIPTION OF THE INVENTION id="p-44" id="p-44" id="p-44" id="p-44" id="p-44" id="p-44" id="p-44" id="p-44" id="p-44" id="p-44" id="p-44"
[0044] The role of the inflammasome/caspasel/pyroptosis axis as a key inflammatory pathway in the context of coronavirus infections and beyond is well known in the art. Furthermore, the relevance of the inflammasome/caspasel/pyroptosis axis specifically in CO VID-19 is also known in the art. Therefore, clinical data that provides a nexus between the 7 inflammasome/caspasel/pyroptosis axis and COVID-19 provides insight for treating COVID-19 by targeting pathways in the inflammasome/caspasel/pyroptosis axis. id="p-45" id="p-45" id="p-45" id="p-45" id="p-45" id="p-45" id="p-45" id="p-45" id="p-45" id="p-45" id="p-45"
[0045] The liver disease and transplant communities provide a window into populations that are especially important to study in light of coronavirus disease 2019 (CO VID-19) as these patients typically have many co-morbidities, including diabetes, obesity and related cardiac issues, cancer, and most notably end-stage organ failure. What these co-morbidities have in common is underlying chronic inflammation involving activation of the inflammasome (Guo H, Callaway IB, Ting IP. Inflammasomes: mechanism of action, role in disease, and therapeutics. Nat Med 2015;21:677-687). What these patients have in common is lethal experiences with COVID-19 (Onder G, Rezza G, Brusaferro S. Case-Fatality Rate and Characteristics of Patients Dying in Relation to COVID-19 in Italy. JAMA 2020). Putting these two factors together caused Applicants to speculate that the inflammasome, and more specifically pyroptosis, are what may drive tragic outcomes for patients with co-morbidities in the face of COVID-19. Applicants observed this phenomenon in a liver transplant patient with several co-morbidities, who rapidly succumbed to the disease, and whose clinical course and immunological phenotype are described in Example 1.
Applicants' finding has been corroborated with at least ten other patients. id="p-46" id="p-46" id="p-46" id="p-46" id="p-46" id="p-46" id="p-46" id="p-46" id="p-46" id="p-46" id="p-46"
[0046] Applicants' findings shed new light on why and how SARS-C0V-2 infections cause such rapid lethality. T cell lymphopenia and lack of COVID specific IgM indicates that the adaptive immune system never properly kicked in. Caspase-1 overexpression in lymphocytes suggests pyroptosis as one of the possible mechanisms of T-cell depletion and functional abnormalities of other lymphocytes (Doitsh et al. Nature 2014;505:509-514). id="p-47" id="p-47" id="p-47" id="p-47" id="p-47" id="p-47" id="p-47" id="p-47" id="p-47" id="p-47" id="p-47"
[0047] Applicants propose that the inflammatory response is secondary to the danger signals from pyroptotic cell death of immune system cells, resulting in a heightened inflammation compared to the one induced by apoptotic tissue cells. The end result is likely a self-damaging shut down of the immune system that further fuels the inflammation created by the viral infection.
Applicants provide data backed connection between caspase-1 and COVID-19, a connection with significant therapeutic implications as rather than inhibition of the inflammatory response, preventing the pyroptotic lymphocyte death fueling the inflammation becomes more critical. id="p-48" id="p-48" id="p-48" id="p-48" id="p-48" id="p-48" id="p-48" id="p-48" id="p-48" id="p-48" id="p-48"
[0048] Based upon knowledge of the inflammasome/caspasel/pyroptosis axis as a key inflammatory pathway in the context of coronavirus infections and the hypotheses regarding COVID-19, clinical data showing inflammasome activation, and more specifically increased levels 8 of lactate dehydrogenase (LDH) Rayamajhi et al. Methods Mol Biol 2013;1040:85-90 and overexpression of caspase-1 and pyroptosis, confirms the hypothesis set forth in FIG. 1. id="p-49" id="p-49" id="p-49" id="p-49" id="p-49" id="p-49" id="p-49" id="p-49" id="p-49" id="p-49" id="p-49"
[0049] By targeting key components of the inflammasome/caspasel/pyroptosis axis to minimize or prevent pyroptosis, Applicants believe the onset and/or severity of lympophenia, hyperinflammation of other immune cells include monocytes and subsequently COVID-19 is delayed and/or mitigated and possibly prevented. id="p-50" id="p-50" id="p-50" id="p-50" id="p-50" id="p-50" id="p-50" id="p-50" id="p-50" id="p-50" id="p-50"
[0050] Rodrigues et al. (J. Exp. Med. 2020 Vol. 218 No. 3 https://rupress.org/jem/arti cl e/218/3/620201707/211560/Inflammasomes-are-activated-in- response-to-SARS) found that the NLRP3 inflammasome is activated in response to SARS-C0V- 2 infection and is active in COVID-19 patients by studying moderate and severe COVID-19 patients, they found active NLRP3 inflammasome in PBMCs and tissues of postmortem patients upon autopsy. Inflammasome-derived products such as Casplp20 and IL-18 in the sera correlated with the markers of COVID-19 severity, including IL-6 and LDH. Moreover, higher levels of IL- 18 and Casplp20 are associated with disease severity and poor clinical outcome. Their results suggest that inflammasomes participate in the pathophysiology of the disease, indicating that these platforms might be a marker of disease severity and a potential therapeutic target for COVID-19. id="p-51" id="p-51" id="p-51" id="p-51" id="p-51" id="p-51" id="p-51" id="p-51" id="p-51" id="p-51" id="p-51"
[0051] Todo et al. (Inflammation Research (2021) 70:7-10 https://doi.Org/10.1007/s00011- 020-01413-2) also identified the presence of NLRP3 inflammasome aggregates in the lungs of fatal COVID-19 pneumonia thus providing the potential molecular link between viral infection and cytokine release syndrome. id="p-52" id="p-52" id="p-52" id="p-52" id="p-52" id="p-52" id="p-52" id="p-52" id="p-52" id="p-52" id="p-52"
[0052] Sars-C0V-2-induced caspase 1 activation and pyroptosis is confirmed in monocytes, which may be as important as in lymphocyte s(see, e.g., https://www.nature.com/articles/s41420- 021-00428-w.pdf). There is not only upregulation of caspasel in SARS-C0V-2 infected monocytes but also effective inhibition of resulting pyroptosis via a caspasel inhibitor. id="p-53" id="p-53" id="p-53" id="p-53" id="p-53" id="p-53" id="p-53" id="p-53" id="p-53" id="p-53" id="p-53"

Immunol. 10:2538 doi: 10.3389/fimmu.2019.02538), all of which are contemplated as pharmaceutical compounds for treating COVID-19 in the present invention. 9 Agent Target(s) Potential mechanism Inhibits ATP-sensitive K+ channels; Glyburide NLRP3 (indirectly) downstream of P2X7 resulting in inhibition of ASC aggregation 16673-34-0 NLRP3 (indirectly) Induces NLRP3 conformational changes secondary to its activation or binding to ASC JC124 NLRP3?

[0054] The present invention relates to determining if a patient is infected with SARS-CoV-2 and whether there is pyroptotic activity in the cells of the patient. For determining infection, a molecular or viral test, usually RT-PCR, is preferred over a serological or antibody test. For determining pyroptotic activity, markers such as NLRP3, IL-1p, IL-18, gasdermin D (GSDMD) and/or caspase 1 are screened at either the nucleic acid or protein level wherein elevated levels of any of the markers are indicative of pyroptosis. id="p-55" id="p-55" id="p-55" id="p-55" id="p-55" id="p-55" id="p-55" id="p-55" id="p-55" id="p-55" id="p-55"
[0055] If a patient tests positive for COVID-19, then the patient is treated with an effective amount of one or more compounds that inhibit one or more pathways of the inflammasome/caspasel/pyroptosis axis. id="p-56" id="p-56" id="p-56" id="p-56" id="p-56" id="p-56" id="p-56" id="p-56" id="p-56" id="p-56" id="p-56"
[0056] Caspase-1 has been identified to be a key enzyme in the inflammasome/caspasel/pyroptosis axis because caspase-1 both activates gasdermin and activates IL-1p and IL-18. Caspase-1 is also known as the interleukin-converting enzyme (ICE). id="p-57" id="p-57" id="p-57" id="p-57" id="p-57" id="p-57" id="p-57" id="p-57" id="p-57" id="p-57" id="p-57"

[0058] The present invention particularly relates to a caspase l/interleukin-1p converting enzyme (ICE) inhibitor in its prodrug form (VX-765), also known as RVT-201, or in its active form (see, e.g., WO01/90063, US7417029, US8329662, US9156880, US9487555, US9994613, and US20200048306, the disclosures of which are incorporated by reference) in treating COVID- 19. In addition to COVID-19, the compound and pharmaceutical compositions thereof are useful as agents to treat interleukin-1- (IL-1), apoptosis-, other forms of cell death such as pyroptotic cell death and necrotic cell death, interferon-6 (IL-6), interferon-17 (IL-17), interferon-18 - (IL-18), interferon-Y (IFNy) or tumor necrosis factor-a (TNFa) mediated disease, including inflammatory diseases, autoimmune diseases, destructive bone disorders, proliferative disorders, infectious diseases, and degenerative diseases. This invention also relates to methods for inhibiting caspase l/ICE activity and decreasing IL-18 production and IFN-y production and methods for treating interleukin-1, apoptosis-, and interferon- y - mediated diseases using the compositions of this invention.

Published online 2021 Jan 12. doi: .1016/j.ejmech.2021.113157. PMCID: PMC7802596). Apart from the direct action of the 16 SARS-Cov 2 virus cytokines have a direct role in the immunopathogenesis of COVID-19 by inducing hyper inflammation and lung injury that defines this disease and the severe phenotype.
Monocytes and macrophages have an important role in respiratory failure during COVID-19; these cells migrate to the lungs, producing pro-inflammatory cytokines, and inducing epithelial damage.
COVID-19 patients present an impaired immune response due to exhausted phenotype and lower effector T cells, CD8+ T lymphocytes, and NK cells, culminating in antiviral immunity loss. While vaccines are now available a proportion of individuals continue to develop a severe phenotype, either from vaccine failure or not being vaccinated. The following are a guide to potential and actual therapies that may mitigate the effects of the virus directly or by reducing the inflammatory consequences. id="p-69" id="p-69" id="p-69" id="p-69" id="p-69" id="p-69" id="p-69" id="p-69" id="p-69" id="p-69" id="p-69"
[0069] Vitamin supplementation enhances immune response: Vitamin A, D, E and C, selenium and zinc. The above supplements have a variety of effects including immune modulation, particularly vitamin D, improving recovery from viral infections, vitamins A and E and zinc and an antioxidant effect selenium and vitamin C. They may have a role in immune "exhaustion". id="p-70" id="p-70" id="p-70" id="p-70" id="p-70" id="p-70" id="p-70" id="p-70" id="p-70" id="p-70" id="p-70"
[0070] Polyclonal (pAbs) and monoclonal (mAbs) antibody-based immunotherapy.
Monoclonal Abs are primarily manufactured however pAbs are from pooled human blood products also known as convalescent plasma (CP) or immune plasma. Antibodies prevent the virus from entering the host cells, blocking receptor ACE2 and directly on the virus (neutralizing antibodies [nAbs] recognize epitopic regions of SARS-C0V-2). On the virus, they prevent its infectivity by activating several pathways, such as the complement system, cell cytotoxicity, and phagocytic clearance. The therapeutic use of mAbs extends to the use of many that block or otherwise modulate part of the antibody cascade. These include anti-JAK, anti-GM-CSF, anti- GM-CSF receptor, anti-M-CSF receptor, anti-CD14, anti-IFN?, anti-VEGF, anti-BKT, anti- CCR5, anti-IL-6, anti-IL-6 receptor, anti-TNFa, anti-ILIB, anti-ILIB receptor, and complement C5 inhibitor. Some antibody drugs are being used to disrupt critical complication that increase morbiditiy and include the hyper-thrombotic state found in critically ill patients by using anti-P- selectin, anti-CTGF, and factor Xlla antagonist mAbs. to restore the exhausted T lymphocytes' and NK cells' immunity, anti-PDl mAbs. Another therapeutic strategy using antibodies is intravenous immunoglobulin (IVIg) that contains polyclonal IgG isolated from healthy donors, which can be further enhanced by using IgG antibodies collected from recovered COVID-19 patients in the same geographical region as the patient. 17 id="p-71" id="p-71" id="p-71" id="p-71" id="p-71" id="p-71" id="p-71" id="p-71" id="p-71" id="p-71" id="p-71"
[0071] Immune cell-based therapy: NK and T cells including CART, stem cells from any source and related products.

Examples Example 1: Adaptive Immune Deficiency in a Lethal Case of CO VID-19 in a Liver Transplant Patient Potential Role for Pyroptosis id="p-132" id="p-132" id="p-132" id="p-132" id="p-132" id="p-132" id="p-132" id="p-132" id="p-132" id="p-132" id="p-132"
[00132] The liver disease and transplant communities provide a window into populations that are especially important to study in light of coronavirus disease 2019 (CO VID-19) as these patients typically have many co-morbidities, including diabetes, obesity and related cardiac issues, cancer, and most notably end-stage organ failure. What these co-morbidities have in common is underlying chronic inflammation involving activation of the inflammasome (Guo H, Callaway IB, Ting IP. Inflammasomes: mechanism of action, role in disease, and therapeutics. Nat Med 2015;21:677-687). What these patients have in common is lethal experiences with COVID-19 (Onder G, Rezza G, Brusaferro S. Case-Fatality Rate and Characteristics of Patients Dying in Relation to COVID-19 in Italy. JAMA 2020). Putting these two factors together caused Applicants to speculate that the inflammasome, and more specifically pyroptosis, are what may drive tragic outcomes for patients with co-morbidities in the face of COVID-19. Applicants successfully explored this hypothesis in a recent liver transplant patient with several co-morbidities, who rapidly succumbed to the disease, and whose clinical course and immunological phenotype are described in this observation. id="p-133" id="p-133" id="p-133" id="p-133" id="p-133" id="p-133" id="p-133" id="p-133" id="p-133" id="p-133" id="p-133"
[00133] A 65-year old woman, with diabetes, hypertension, obesity, cirrhosis from primary sclerosing cholangitis, and a MELD score of 40 received a liver transplant in early 2020 (FIG. 2A) 36 and was put on standard immunosuppression. 26 days post-transplant she was discharged into a sub-acute rehab facility, where Applicants suspect she contracted SARSCoV-2 as it later turned out to home three COVID-19 cases. Two days after returning home from the facility, she presented emergently with fever, dry cough, and shortness of breath for two days and was tested for COVID- 19. A chest x-ray revealed multilobular interstitial infiltrates (FIG. 2B). She rapidly desaturated, got intubated, and underwent cardiopulmonary resuscitation for pulselessness, with return of spontaneous circulation. She was started on ARDSnet ventilation and hypothermia protocols in intensive care. Laboratory results showed marked lymphopenia and elevated inflammatory markers (FIG. 2A). She was treated with Hydroxychloroquine and Azithromycin after confirming COVID-19 the next day. Her neurological exam and head CT upon rewarming showed evidence of anoxic brain injury. ARDS and poor neurological status persisted (FIG. 2B), and she succumbed to COVID-19 six days after admission. id="p-134" id="p-134" id="p-134" id="p-134" id="p-134" id="p-134" id="p-134" id="p-134" id="p-134" id="p-134" id="p-134"
[00134] Although evidence for activation of antigen presenting cells (APCs) and involvement of Type-1-interferon response, as indicated by upregulation of CDllb and CD38 on monocytes and tetherin on B-cells, suggested innate immune activation there was a profound adaptive immune dysfunction (FIG. 2A and FIG. 3). Notably, Applicants found no B-cell memory cells and absence of SARS-C0V-2-specif1c IgG and IgM. Moreover, she exhibited profound T-cell lymphopenia, further underscored by absence of T-regulatory cells, low T-follicular helper cells, overexpression of CD38 in CD8 T-cells, and poor STAT-4 phosphorylation of CD4 T-cells upon IL-12 stimulation. Finally, high levels of lactate dehydrogenase (LDH) (FIG. 2A) and a global increase in caspase-1 staining (FIG. 3) in lymphocyte shinted at pyroptosis (Rayamajhi et al. Methods Mol Biol 2013;1040:85-90 and Doitsh et al. Nature 2014;505:509-514), which may explain her poor immune response. id="p-135" id="p-135" id="p-135" id="p-135" id="p-135" id="p-135" id="p-135" id="p-135" id="p-135" id="p-135" id="p-135"
[00135] Applicants' findings may shed new light on why and how SARS-C0V-2 infections cause such rapid lethality. T cell lymphopenia and lack of CO VID specific IgM indicates that the adaptive immune system never properly kicked in. Caspase-1 overexpression in lymphocytes suggests pyroptosis as one of the possible mechanisms of T-cell depletion and functional abnormalities of other lymphocytes (Doitsh et al. Nature 2014;505:509-514). This finding, even though limited to one patient presented here and potentially exacerbated by immunosuppressive medication, brings Applicants' attention to a COVID-19 induced acute immunodeficiency, resulting from the necrotic cell death of lymphocytes. Applicants propose that the inflammatory 37 response is secondary to the danger signals from necrotic cell death of immune system cells, resulting in a heightened inflammation compared to the one induced by dying tissue cells (Matzinger P. Tolerance, danger, and the extended family. Annu Rev Immunol 1994; 12:991- 1045). The end result is likely a self-damaging shut down of the immune system that further fuels the inflammation created by the viral infection. Applicants provide data backed connection between caspase-1 and CO VID-19, a connection with significant therapeutic implications as rather than inhibition of the inflammatory response, preventing the pyroptotic lymphocyt edeath fueling the inflammation becomes more critical. id="p-136" id="p-136" id="p-136" id="p-136" id="p-136" id="p-136" id="p-136" id="p-136" id="p-136" id="p-136" id="p-136"
[00136] This patient was a 65-year-old woman with decompensated liver cirrhosis from primary sclerosing cholangitis complicated by jaundice, ascites, hepatic encephalopathy, and portal hypertension with esophageal varices, and a history of chronic portal vein thrombosis requiring anti coagulation with warfarin and recanalization with transjugular intrahepatic portosystemic shunt (TIPS). Her model for end-stage liver disease (MELDNa) score at time of transplant was 40.
Past medical history included insulin dependent diabetes mellitus, obesity (body mass index (BMI) 32), hypertension, and gout. Past surgical history included open cholecystectomy, umbilical hernia repair, and hysterectomy. id="p-137" id="p-137" id="p-137" id="p-137" id="p-137" id="p-137" id="p-137" id="p-137" id="p-137" id="p-137" id="p-137"
[00137] She underwent orthotopic liver transplantation in early 2020 (see Supplementary Table 1 for her pre-transplant laboratory panel, noted as day -38 from the onset of CO VID-19 symptoms).
She received an organ from a 19-year-old male brain-dead deceased donor. Donor / recipient cytomegalovirus (CMV) and Epstein-Barr virus (EBV) serologies were +/+ and +/+, respectively.
The liver transplant was performed in a standard fashion (vena cava replacement without veno- venous bypass) with standard portal vein and arterial anastomoses. Intraoperative findings included significant portal hypertension with venous collaterals, dense adhesions from prior open cholecystectomy, intraoperative right atrial thrombus which resolved with tissue plasminogen activator (tPA) lysis, and significant blood loss due to coagulopathy. id="p-138" id="p-138" id="p-138" id="p-138" id="p-138" id="p-138" id="p-138" id="p-138" id="p-138" id="p-138" id="p-138"
[00138] After successful liver transplantation the patient was transferred to the intensive care unit (ICU) with external biliary drainage and open abdomen. After resolution of the coagulopathy, she returned to the operating room (OR) 72 hours later in stable conditions for biliary reconstruction and closure of the abdomen. id="p-139" id="p-139" id="p-139" id="p-139" id="p-139" id="p-139" id="p-139" id="p-139" id="p-139" id="p-139" id="p-139"
[00139] Induction immunosuppression consisted of methylprednisolone (1g intravenous therapy (i.v.) post-operative day (POD) 0) and basiliximab (20mg i.v. POD 2 and 5, respectively). 38 Maintenance immunosuppression regimen included tacrolimus (2 mg orally (p.o.) twice per day), mycophenolate-mofetil (1g p.o. twice per day), and standard steroid taper. The patient received standard anti-infectious prophylaxis with sulfamethoxazole-trimethoprim, nystatin, and ganciclovir. id="p-140" id="p-140" id="p-140" id="p-140" id="p-140" id="p-140" id="p-140" id="p-140" id="p-140" id="p-140" id="p-140"
[00140] Her initial post-transplant course was characterized by slow normalization of serum bilirubin levels and acute renal failure requiring renal replacement therapy (both of which resolved prior to discharge; see also Supplementary Table 1 for her laboratory panel upon discharge, noted as day -12 from the onset of CO VID-19 symptoms), and anemia requiring transfusion of two units of packed red blood cells (PRBCs). In addition, her post-transplant course was notable for mental status changes responding to Quetiapine without intracranial abnormal imaging findings, temporary dysphonia from vocal cord paralysis, dysphagia requiring enteral tube feeding via naso- jejunal tube and Clostridium dijfficile-negatwe diarrhea, which improved after resumption of regular diet. Incidentally, the patient was found to have a chronic left humeral neck fracture on routine post-operative chest x-ray, which was treated conservatively. id="p-141" id="p-141" id="p-141" id="p-141" id="p-141" id="p-141" id="p-141" id="p-141" id="p-141" id="p-141" id="p-141"
[00141] On POD 26, the patient was discharged to a subacute rehab (SAR) facility in stable condition with normal allograft function (see Supplementary Table 1 for her labs upon discharge, noted as day -12 from the onset of COVID-19 symptoms). She returned for routine follow ups over the coming weeks, which all showed normal labs, including (coincidently) on the very day that she later reported first feeling symptoms later that night (see Supplementary Table 1 for her labs that day, noted as day 0 from the onset of COVID-19 symptoms). id="p-142" id="p-142" id="p-142" id="p-142" id="p-142" id="p-142" id="p-142" id="p-142" id="p-142" id="p-142" id="p-142"
[00142] Two days after discharge from the rehabilitation facility, she presented to Applicants' emergency department with fever 37.6?, dry cough, and shortness of breath for two days. On presentation the peripheral oxygen saturation (S-O2) was 96% on room air; her blood pressure and heart rate where within normal limits. A nasopharyngeal swab specimen was obtained and sent for COVID-19 real-time PCR testing (see methods below for test relevant details). A chest x-ray revealed multilobular bilateral interstitial infiltrates (see FIG. 2B). While completing evaluation in the emergency department, the patient rapidly desaturated (S-O2 20-30%) and became unresponsive requiring bedside intubation. She was found to be pulseless and underwent immediate cardiopulmonary resuscitation, including chest compressions with return of spontaneous circulation. Upon transfer to intensive care ARDSnet ventilation and hypothermia protocols were initiated. Laboratory results showed marked lymphopenia and elevated 39 inflammatory markers (see FIG. 2A). Empiric antibiotics (Cefepime (2g i.v. ql2h) and Vancomycin (1 g i.v.) were administered for potential community acquired pneumonia.
Hydroxychloroquine (400mg twice per day followed by 200 mg twice per day) and Azithromycin (250 mg i.v. q24h) were added the following day upon positive result of the nasopharyngeal swab test for COVID-19. The neurological exam and head CT findings upon rewarming showed evidence of diffuse anoxic brain injury. Poor neurological status and ARDS requiring ventilation (Fi02 >= 60%) persisted over subsequent days. Repeat CT imaging of the head and chest (see FIG. 2B) showed no improvement in terms of anoxic brain injury and ARDS, and she succumbed to COVID-19 six days after admission, eight days after first experiencing symptoms. id="p-143" id="p-143" id="p-143" id="p-143" id="p-143" id="p-143" id="p-143" id="p-143" id="p-143" id="p-143" id="p-143"
[00143] The patient was enrolled in a MedStar Georgetown Transplant Institute biorepository study (IRB #2017-0365). Written informed consent was obtained prior to inclusion into that study.
Ethical utilization of transplant organs and tissue abided by principles in the Declaration of Helsinki. The donor organ was not obtained from an executed prisoner or otherwise institutionalized person. id="p-144" id="p-144" id="p-144" id="p-144" id="p-144" id="p-144" id="p-144" id="p-144" id="p-144" id="p-144" id="p-144"
[00144] Clinical specimens of the nasopharynx for SARS-C0V-2 testing were obtained, handled, and processed via real-time polymerase chain reaction assay as previously reported by Applicants' hospital group (Iqbal et al. N Engl J Med 2020 and Corman et al. Euro dSurveill 2020;25). Briefly, viral nucleic acid was extracted by the MagNA Pure 96 IVD automated instrument (ROCHE Diagnostics) from nasopharyngeal swab specimen. Real-Time PCR was performed using the COBAS ® Z480 Real-Time PCR System (ROCHE Diagnostics). id="p-145" id="p-145" id="p-145" id="p-145" id="p-145" id="p-145" id="p-145" id="p-145" id="p-145" id="p-145" id="p-145"
[00145] Patient samples for clinical immunophenotyping were obtained on day 4 and day 7 after onset of symptoms. Images shown in FIGS. 3A-E are from day 7 sample. A healthy sample was used as a matched control. Samples were processed in accordance with Amerimmune's clinical safety SOPs. Appropriate PPE were used when processing samples. id="p-146" id="p-146" id="p-146" id="p-146" id="p-146" id="p-146" id="p-146" id="p-146" id="p-146" id="p-146" id="p-146"
[00146] Peripheral blood from venipuncture was drawn into EDTA and heparin coated vacutainer tubes (BD Bioscience) for clinical immunophenotyping. Whole blood collected in EDTA tubes was immunostained per the clinical standard immunophenotyping protocol (Amerimmune LLC, Fairfax, VA). The samples were stained with the antibody combinations as indicated in the supplemental Table 1 for 30 minutes at 4°C. Red blood cells were lysed using BD FACS lysis solution (BD Bioscience, Jan Jose, CA) as per manufacture directions. 40 id="p-147" id="p-147" id="p-147" id="p-147" id="p-147" id="p-147" id="p-147" id="p-147" id="p-147" id="p-147" id="p-147"
[00147] Peripheral blood mononuclear cells (PBMC) were separated from 2 mL of whole blood diluted 1:1 with phosphate buffered saline pH 7.2 (PBS) (Thermo Fisher Scientific, Carlsbad, CA) using Lymphoprep (Stem cell Technologies, Cambridge, MA) and Accuspin tubes (Sigma- Aldrich, St. Louis, MO) as per manufactures directions. PBMCs' were washed in PBS and resuspended in 0.4 mL PBS. 100 pL of the PBMCs were immunostained with a mixture of antibodies as indicated in supplemental Table 2 at 4? for 1 hour. Cells were washed and resuspended in PBS prior to acquisition. id="p-148" id="p-148" id="p-148" id="p-148" id="p-148" id="p-148" id="p-148" id="p-148" id="p-148" id="p-148" id="p-148"

[00150] Apoptosis and pyroptosis were measured by flow cytometry using fluorescent-labeled inhibitors of caspase probe assay, FLICA, as per manufactures protocol (Immunochemistry Technologies, Minneapolis, MN). FAM-FLICA probes specific for Caspase 1 and Caspase 3/7 were directly added to 100 pl PBMC, incubated for 1 hour at 37°C. Cells were washed 3 times with wash buffer to remove unbound FLICA probes. Cells were stained for CD45 PE-CY7 [HI30], 41 CD3 AF700 [UCHT1], CD4 PE [RPA-T4], CD45RO PerCP-EF710 [UCHL1] and Viability Dye 780 (Thermo Fisher Scientific, Carlsbad, CA) to identify viable CD45+CD3+CD4+CD45RO- T cells. An additional singlet gate was incorporated in the gating scheme to identify singlets. id="p-151" id="p-151" id="p-151" id="p-151" id="p-151" id="p-151" id="p-151" id="p-151" id="p-151" id="p-151" id="p-151"
[00151] Whole blood was stimulated with IL-12 (100 ng/ml) for 0, 15, 30, 60 and 120 minutes.
Cells were stained as per the BD Phosflow protocol. In brief, cells were stained with CD3 APC [SK7], CD4 PE-CY7 [SK3], CD45RO BV421 [UCHL1] and p-STAT4 [38/p-Stat4], CD3+CD4+ T cells were identified from the lymphocyte and singlet gate described previously. The CD45RO/pSSTAT4 plots are gated on CD3+CD4+ T cells. id="p-152" id="p-152" id="p-152" id="p-152" id="p-152" id="p-152" id="p-152" id="p-152" id="p-152" id="p-152" id="p-152"
[00152] The samples were acquired on a 3 laser BD FACS Canto 10. CS&T beads (BD Bioscience, San Jose, CA) were acquired daily to ensure consistent performance of the CantolO.
The BD FACS Canto 10 was cleaned with 10 minutes of 10% bleach and water following acquisition of samples. The CANTO 10 utilized for this study has been validated for T, B, NK and Dendritic cell immunophenotyping clinical diagnostic testing. Denovo FCS Express v6 clinical edition (De Novo Software, Pasadena, CA) was used for flow cytometric analyses. id="p-153" id="p-153" id="p-153" id="p-153" id="p-153" id="p-153" id="p-153" id="p-153" id="p-153" id="p-153" id="p-153"
[00153] Monocytes were identified by a standard gating strategy utilizing CD14, CD16 and HLADR to identify classical, intermediate and nonclassical monocytes. CD38 and CDllb MFI and percent positive were examined form CD14++CD16+ intermediate monocytes. id="p-154" id="p-154" id="p-154" id="p-154" id="p-154" id="p-154" id="p-154" id="p-154" id="p-154" id="p-154" id="p-154"
[00154] Lymphocyte swere identified using a standard gating schematic incorporated gating of lymphocytes on a FSC/SSC plot and singlets on a FSC-A/FSC-H plot. From the lymphocyte plots, T cells were identified as CD45+ on a CD45/SSC plot. CD45+CD3+ cells were gated on a CD3/SSC plot. CD4+ and CD8+ T cells were identified by CD4/CD8 CD3+ gating. Subsequent T cell subpopulations as indicated in FIG. 3B were identified from CD45+CD3+CD4+ or CD8+ cells. id="p-155" id="p-155" id="p-155" id="p-155" id="p-155" id="p-155" id="p-155" id="p-155" id="p-155" id="p-155" id="p-155"
[00155] Perforin and Granzyme B immune-phenotyping was done on CD8+ T cells and NK cells. Lymphocytes were identified as described previously on a FSC/SSC and FSCA/FSC-H plots.
NK and T cells were identified by a CD56/TCR a/p plot. NK cells were identified as CD56+TCR a/p־ and T cells were identified as TCRa/p+CD56- and CD8+ on a CD8/SSC plot. Identified specific populations were examined for perforin and granzyme staining, using an FMO control for both perforin and granzyme. id="p-156" id="p-156" id="p-156" id="p-156" id="p-156" id="p-156" id="p-156" id="p-156" id="p-156" id="p-156" id="p-156"
[00156] From the lymphocyte gating plots, B cells were identified as CD45+, then CD20+ from a CD20/SSC plot. All B cell subpopulations were identified from the CD45+CD20+ population. 42 id="p-157" id="p-157" id="p-157" id="p-157" id="p-157" id="p-157" id="p-157" id="p-157" id="p-157" id="p-157" id="p-157"
[00157] For SARS-CoV-2 IgG and IgM antibody detection, Applicants used four lateral flow assay kits for COVID IgG and / or IgM (Dynamiker Technology, Tianjin, China; Wondfo, Guangdong, China; and Shenyang Union Biotechnologies, Liaoning, China), one chemiluminescent kit for COVID-19 IgG and IgM (Xincheng Biotechnologies, Sichuan, China), and ELISA for COVID-19 IgG/ IgM (Antibody Biopharma, Gaithersburg, MD, USA).

[00162] First, Applicants' patients also exhibited low T-cell counts and lymphopenia. In addition, Applicants see comorbidities with an inflammatory profile as especially high-risk for a morbid COVID-19 course (Guo et al. Nat Med 2015;21:677-687). Given this finding and studies emphasizing the role of the inflammasome in coronaviruses (Shi et al. Cell Death Discov. 5, 101 (2019)), Applicants analyzed caspase-1 activity in their patients. Critically, Applicants found a strong upregulation of caspase-1 activity in both T-cells and lymphocytes as well as high LDH levels across their patients, suggesting pyroptosis as a cause of lymphopenia and a driver of heightened inflammation in COVID-19 similar to SARS-CoV-1 (Yue et al. Cell Death Dis 9, 904 (2018)). This insight has therapeutic implications beyond transplantation as it implies upstream prevention of pyroptosis may be beneficial.

[00225] For Stage 1, the sample size of 4 subjects per group (2 on VX-765, 2 on placebo) is designed to provide an initial assessment of safety and tolerability for the initial doses of VX-765.
The Stage 2 sample size of 28 patients in a VX-765 treatment group (i.e., the 2 VX-765 treatment groups combined) provides a 95% probability that an AE with an underlying rate of 10% occurs in these patients. Additionally, in Stage 2, a sample size of 28 patients per group (i.e., pooling the Stage 2 placebo groups and the VX-765 groups) provides approximately 80% power to detect a treatment difference at the 2-sided 0.05 Type I error rate based on a using a CMH row mean score difference test controlling for the baseline score. id="p-226" id="p-226" id="p-226" id="p-226" id="p-226" id="p-226" id="p-226" id="p-226" id="p-226" id="p-226" id="p-226"

[00269] The purpose of this randomized study is to obtain safety, tolerability and efficacy data in hospitalized patients with Covid-19 infection treated with VX-765 in addition to standard of care. The study drug/placebo is delivered every 8 hours for up to 15 days. 53 id="p-270" id="p-270" id="p-270" id="p-270" id="p-270" id="p-270" id="p-270" id="p-270" id="p-270" id="p-270" id="p-270"
[00270] The study is conducted in two stages. Stage 1 is single-blind (patient is blinded, but the physicians and sponsor is unblinded), whereas Stage 2 is double-blind (patient and physician is blinded, sponsor is unblinded). In Stage 1, 24 patients is treated in groups of 4, randomized 1:1 to VX-765 or placebo and treated with escalating doses. The first group (n=4) is treated with VX-765 or placebo at 0.5mg (in 2.5mls normal saline). The second group (n=4) is treated with VX-765 or placebo at l.Omg (in 5 ml normal saline). Subsequent groups (each group n=4) is treated with VX- 765 or placebo at 2.0mg (in lOmls normal saline), 3.0mg (in 15mls normal saline), 4.0mg (in 20mls normal saline) or 5.0mg (in 25mls normal saline). In Stage 2, 28 patients is randomized 1:1 to VX- 765 or placebo at the highest dose without any drug-related adverse events, and another 28 patients is randomized 1:1 to VX-765 or placebo at the dose just below the highest dose without any drug- related adverse events. id="p-271" id="p-271" id="p-271" id="p-271" id="p-271" id="p-271" id="p-271" id="p-271" id="p-271" id="p-271" id="p-271"

[00275] a; To balance the distribution of oxygen support 1)etween the two groups as an indicator of severe respiratory failure, randomization in Stage 2 is stratified on the basis of respiratory support methods at the time of enrollment: no oxygen support with nasal duct or mask, or high flow oxygen, noninvasive ventilation, or invasive ventilation including ECMO. 54 id="p-276" id="p-276" id="p-276" id="p-276" id="p-276" id="p-276" id="p-276" id="p-276" id="p-276" id="p-276" id="p-276"
[00276] Approximately 80 subjects are entered at up to 10 sites in the USA. Hospitalized patients with illness of any duration are assessed for eligibility on the basis of a positive reverse transcriptase polymerase chain reaction (RT-PCR) assay or other commercial or public health assay for SARS-C0V-2 in a respiratory tract sample. Patients who test positive in any sample <72 hours prior to randomization are eligible. In addition to a positive SARS-C0V-2 test, patients are required to have crackles/rales and an SpO2 < 94% on room air, or respiratory failure requiring supplemental oxygen/ventilation, or radiographic infiltrates by imaging (CT, CXR). id="p-277" id="p-277" id="p-277" id="p-277" id="p-277" id="p-277" id="p-277" id="p-277" id="p-277" id="p-277" id="p-277"

[00278] In addition, patients receive study medication/placebo, administered three times a day for up to 15 days. The lowest dose group receives 10 mg/kg orally. The highest dosing group receives 100 mg/kg orally. Medication is discontinued if the patient improves to the point where they can be discharged. id="p-279" id="p-279" id="p-279" id="p-279" id="p-279" id="p-279" id="p-279" id="p-279" id="p-279" id="p-279" id="p-279"

[00376] All adverse events, exacerbations of concomitant illnesses, or events known to be related to underlying disease processes or concomitant medications are to be recorded on the CRF throughout the study. If a pre-existing condition worsens on study, the date on which the exacerbation began should be recorded. Onset dates for study treatment-related adverse events must be on or after the date of initial study treatment use. The need to record an adverse event on the CRF is not dependent on whether the adverse event is associated with the use of the study medication. In order to avoid vague, ambiguous or colloquial expressions, the adverse event should be recorded in standard medical terminology. id="p-377" id="p-377" id="p-377" id="p-377" id="p-377" id="p-377" id="p-377" id="p-377" id="p-377" id="p-377" id="p-377"
[00377] Adverse event recording includes the date of onset, severity, duration, whether or not the study medication was discontinued because of the event, the treatment given and the outcome.
The investigator must also assess whether the event was related to the study medication, concurrent drug therapy, underlying disease, a combination of these factors, or if it is unknown. Subjects with an adverse event should be carefully followed to determine outcome.d id="p-378" id="p-378" id="p-378" id="p-378" id="p-378" id="p-378" id="p-378" id="p-378" id="p-378" id="p-378" id="p-378"

[00394] Adverse Event: Any untoward medical occurrence in a subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An adverse event can be any unfavorable sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of the investigational drug, whether or not considered related to the investigational drug. id="p-395" id="p-395" id="p-395" id="p-395" id="p-395" id="p-395" id="p-395" id="p-395" id="p-395" id="p-395" id="p-395"

[00402] There is a distinction between the severity and the seriousness of an adverse event.
Severe is a measurement of intensity, thus a severe reaction is not necessarily a serious adverse event. For example, a headache may be severe in intensity, but would not be serious unless it met one of the criteria for serious adverse events listed previously. id="p-403" id="p-403" id="p-403" id="p-403" id="p-403" id="p-403" id="p-403" id="p-403" id="p-403" id="p-403" id="p-403"

[00404] Adverse events (AEs) and serious adverse events (SAEs) are collected from the first dose of IP is administered until 28 days after the last dose of IP. Medical occurrences that began prior to the start of study treatment, but after obtaining informed consent were recorded on the Medical Hi story/Curr ent Medical Conditions CRF. The investigator or site staff is responsible for the detection and documentation of events meeting the criteria and definition of an adverse event or serious adverse event, as provided in the study protocol, However, any SAEs assessed as related to study participation (e.g., dosing, protocol mandated procedures, invasive tests, or change in existing therapy) or related to a concomitant medication is recorded from the time a subject consent to participate in the study up to and including any follow-up contact. id="p-405" id="p-405" id="p-405" id="p-405" id="p-405" id="p-405" id="p-405" id="p-405" id="p-405" id="p-405" id="p-405"
[00405] In the event of an AE or SAE, it is the responsibility of the Investigator to review all documentation (e.g., hospital progress notes, laboratory, and diagnostics reports) relative to the event and attempt to establish a diagnosis of the event based on signs, symptoms, and other clinical 63 information. The diagnosis was to be documented as the adverse event or serious adverse event and not the individual's signs/symptoms. Once an Investigator becomes aware that a SAE has occurred in a study subject, they are' to report the information within 24hrs and provide an assessment of causality. id="p-406" id="p-406" id="p-406" id="p-406" id="p-406" id="p-406" id="p-406" id="p-406" id="p-406" id="p-406" id="p-406"

[00407] Under IND regulations, 21 CFR Part 312.64, investigators are required to notify the Sponsor promptly, within 24 hours of the sites' notification of any SAEs, deaths, or life-threatening problems with the investigational drug. This regulation also requires that if the adverse event is alarming, the investigator must notify the Sponsor immediately. id="p-408" id="p-408" id="p-408" id="p-408" id="p-408" id="p-408" id="p-408" id="p-408" id="p-408" id="p-408" id="p-408"
[00408] A Serious Adverse Event (SAE) is a significant hazard, contraindication, or precaution considered to be serious. This includes, but is not limited to, blood dyscrasias, endocrine disturbances, hemorrhage from any site, or severe skin disorder. Additional examples are intensive treatment for allergic bronchospasm, blood dyscrasias or convulsions. id="p-409" id="p-409" id="p-409" id="p-409" id="p-409" id="p-409" id="p-409" id="p-409" id="p-409" id="p-409" id="p-409"
[00409] Subj ects who experience a SAE must be given appropriate examinations and treatment.
The investigator must provide written information to the sponsor as soon as possible. id="p-410" id="p-410" id="p-410" id="p-410" id="p-410" id="p-410" id="p-410" id="p-410" id="p-410" id="p-410" id="p-410"
[00410] When an investigator is in doubt when to report an event, the investigator should err on the side of caution. id="p-411" id="p-411" id="p-411" id="p-411" id="p-411" id="p-411" id="p-411" id="p-411" id="p-411" id="p-411" id="p-411"
[00411] All appropriate SAEs is reported immediately to appropriate regulatory authorities by the Sponsor. A copy of all FDA reportable serious adverse events is mailed to all investigators participating in ongoing clinical studies with the study medication in order to permit prompt notification of the appropriate institutional review board (IRB). id="p-412" id="p-412" id="p-412" id="p-412" id="p-412" id="p-412" id="p-412" id="p-412" id="p-412" id="p-412" id="p-412"

[00413] In medical emergencies, the investigator should use medical judgment and remove the subject from immediate hazard and decide whether the subject may continue in the study. The IRB should also be notified as to the type of emergency and the course of action. The CRF for the subject must describe the departure from the protocol and state the reason. id="p-414" id="p-414" id="p-414" id="p-414" id="p-414" id="p-414" id="p-414" id="p-414" id="p-414" id="p-414" id="p-414"

[00415] A Data Safety and Monitoring Board (DSMB) has been established to monitor the safety of the subjects during the study. The DSMB includes members who are independent of this study and its Sponsor Team with relevant clinical expertise, including a good understanding of the safety of medications for respiratory illnesses. These members include a statistician, an infectious 64 disease specialist and/or a pulmonologist. The methodology and the operating procedures for the safety reviews is developed by the infectious disease specialist and/or pulmonologist in collaboration with the sponsor and is documented in the DSMB Charter. The DSMB is not blinded.
They review all SAEs and determine whether the study can proceed or whether protocol modifications are required. id="p-416" id="p-416" id="p-416" id="p-416" id="p-416" id="p-416" id="p-416" id="p-416" id="p-416" id="p-416" id="p-416"

[00417] During the 15-day dosing period, it is anticipated that no more than 2 subjects out of 40 (5.0%) have an adverse event of grade 4 or 5 that is at least possibly related to VX-765. Should there be more than 2 subjects with an adverse event grade 4 or 5 that is at least possibly related to VX-765 in the cohort of subjects, the study is put on an immediate clinical hold. id="p-418" id="p-418" id="p-418" id="p-418" id="p-418" id="p-418" id="p-418" id="p-418" id="p-418" id="p-418" id="p-418"

[00424] Neither the investigator shall modify this protocol without first obtaining concurrence of the other in writing. All changes must be submitted to the IRB. Protocol modifications which impact subject safety, or the validity of the study must be approved by the IRB and submitted to the FDA before implementation. In the case of a medical emergency to increase safety of subjects, a change may be made after discussion with the sponsor. In these instances, the IRB and FDA is notified as soon as possible. id="p-425" id="p-425" id="p-425" id="p-425" id="p-425" id="p-425" id="p-425" id="p-425" id="p-425" id="p-425" id="p-425"

[00463] For Stage 1, the sample size of 4 subjects per group (2 on VX-765, 2 on placebo) is designed to provide an initial assessment of safety and tolerability for the initial doses of VX-765.
The Stage 2 sample size of 28 patients in an VX-765 treatment group (i.e., the 2 VX-765 treatment groups combined) provides a 95% probability that an AE with an underlying rate of 10% occurs in these patients. Additionally, in Stage 2, a sample size of 28 patients per group (i.e., pooling the Stage 2 placebo groups and the VX-765 groups) provides approximately 80% power to detect a treatment difference at the 2-sided 0.05 Type I error rate based on a using a CMH row mean score difference test controlling for the baseline score. This assumes the following day 15 distribution for the seven-category disease severity score. Power was estimated based on the distribution of scores presented using the Mantel-Haenszel mean score statistic with modified ridit scoring. id="p-464" id="p-464" id="p-464" id="p-464" id="p-464" id="p-464" id="p-464" id="p-464" id="p-464" id="p-464" id="p-464"

[00696] FDA Data Standard Guidelines are followed. Continuous variables are summarized using the number of observations, number of observations above the limit of quantification (if applicable), mean, standard deviation (SD) median, and range. Categorical variables are summarized using frequency counts and percentages. Comparison of belnacasan and placebo 83 groups utilize Poisson regression for counts, Cox proportional hazards regression for time-to-event data and mixed effects models for continuous and categorical data obtained over study days. id="p-697" id="p-697" id="p-697" id="p-697" id="p-697" id="p-697" id="p-697" id="p-697" id="p-697" id="p-697" id="p-697"

[00698] All safety & tolerability analyses are performed on the Safety Population. The safety data is presented in individual listings and summary tables. Overall safety is assessed by the number of belnacasan dosed subjects experiencing a grade 4 or 5 SAE during the trial. Of 24 subjects enrolled in the belnacasan group, 3 or more developing a grade 4 or 5 SAE potentially related to belnacasan would be considered unlikely due to chance. Therefore, belnacasan is determined safe if no more than 2 subjects develop a grade 4 or 5 SAE in the belnacasan group potentially related to belnacasan. If 3 or more subjects in the belnacasan group develop SAEs potentially related to belnacasan during the trial, belnacasan is considered not safe, and the trial stopped or placed on clinical hold as noted. id="p-699" id="p-699" id="p-699" id="p-699" id="p-699" id="p-699" id="p-699" id="p-699" id="p-699" id="p-699" id="p-699"

[00700] Event counts over 60 days are analyzed by Poisson regression. Time to events is analyzed by Cox regression. Differences between belnacasan and placebo with respect to change in continuous endpoints are assessed by mixed effects models for continuous repeated measures data and mixed effects logistic models for repeated categorical variables. Endpoint proportions of belnacasan and placebo groups are assessed by contingency table analysis (chi-square). id="p-701" id="p-701" id="p-701" id="p-701" id="p-701" id="p-701" id="p-701" id="p-701" id="p-701" id="p-701" id="p-701"

[00702] As this is a proof-of-concept study, it is likely not be powered to detect belnacasan - placebo differences that are clinically meaningful. For example, the observed difference in endpoint rate ratios would need to be over 60% to achieve 80% power with an alpha error rate of % for 24 subjects in each group. This study provides an estimate of the belnacasan effect size to inform a larger trial where a more clinically meaningful difference can be detected. id="p-703" id="p-703" id="p-703" id="p-703" id="p-703" id="p-703" id="p-703" id="p-703" id="p-703" id="p-703" id="p-703"

[00704] For more than one year, coronavirus disease 2019 (COVID-19) - an acute respiratory disease caused by SARS-C0V-2 that also has profound multi-systemic inflammatory involvement - has cost countless lives and livelihoods, especially for vulnerable populations with comorbidities characterized by chronic inflammation. The full spectrum of COVID-19 ranges from asymptomatic, to a mild, self-limiting respiratory tract illness, to severe progressive pneumonia, multi-organ failure, and death [1], Since its first discovery, the virus has continued to spread, even 84 with attempted control with a variety of public health measures. There are more than 32 million cases in the United States, accounting for a quarter of the worlds documented cases, and over 570,000 deaths [2], In general, there is likely an underestimate of total cases since the prevalence of asymptomatic carriers is yet unknown. What is clear, is that individuals at highest risk are those over 65 years and / or those with concomitant chronic conditions most notably hypertension, diabetes, pre-diabetes, obesity, chronic cardiorespiratory disorders and chronic renal and liver impairment [1, 3-6], While there are racial disparities in the greater number of Black and Hispanic patients experiencing a more severe course there is no evidence that this is related to anything other than underlying comorbidities and socioeconomic factors, often limiting their ability to socially distance. id="p-705" id="p-705" id="p-705" id="p-705" id="p-705" id="p-705" id="p-705" id="p-705" id="p-705" id="p-705" id="p-705"
[00705] There have been promising scientific breakthroughs for preventing and treating severe COVID-19, including via vaccines, monoclonal antibody and steroid treatments. However, there is to-date no targeted treatment for SARS-C0V-2-mediated inflammation and subsequent complications in COVID-19. In general drug treatments aimed at the virus have so far not lived up to their promise. Most notably the nucleotide analog remdesivir was demonstrated to mitigate the course of the illness when given early in the course [7], Subsequent data however failed to show a benefit. While antibody for treatment has been available the uptake of this therapy has been limited by parenteral administration. While efficacious in patients with mild to moderate COVID- 19 who are at high risk of progressing to severe disease [8], monoclonal antibodies (e.g., bamlanivimab, casirivimab, and imdevimab) are costly and their administration is complicated for outpatients and providers as it is given intravenously, in an hour long infusion that must take place in a separate unit since recipients are infectious. A late 2020 report from the Department of Health and Human Services found that only 5-20% of available supply had been used. Currently the most widely accepted and available treatment is dexamethasone having shown a clear benefit in seriously affected, hospitalized patients [9], id="p-706" id="p-706" id="p-706" id="p-706" id="p-706" id="p-706" id="p-706" id="p-706" id="p-706" id="p-706" id="p-706"
[00706] The most hopeful remedy for the population at large is vaccination and at this time vaccines from three sources (Pfizer/BioNTech, Moderna, Johnson & Johnson) have been authorized for emergency use in the United States after having demonstrated the ability to prevent disease in up to 95% of individuals [10], However, vaccines may not be sufficient to address COVID-19 across the US population for four reasons. First, vaccine hesitancy persists (https://aspe.hhs.gov/pdf-report/vaccine-hesitancy). Second, vaccination may only confer 85 immunity for a limited number of months, necessitating the need for booster shots (https://www.cnbc.com/2021/04/21/scientist-who-helped-develop-pf1zer-biontech-covid- vaccine-agrees-third-shot-is-needed-as-immunity-wanes.html), which may not be taken, or taken on time, by all who need them. Third, immunocompromised people, such as transplant recipients on immunosuppressive medication, have recently been shown to not develop sufficient antibodies through vaccination [11, 12], Fourth, it remains to be seen to what extent vaccines are effective against emerging new variants with immune-escape properties [13-15], id="p-707" id="p-707" id="p-707" id="p-707" id="p-707" id="p-707" id="p-707" id="p-707" id="p-707" id="p-707" id="p-707"
[00707] Moreover, given that even mild COVID-19 cases can result in devastating, likely inflammatory-driven, persisting effects (https://www.cdc.gov/coronavirus/2019-ncov/long-term- effects.html), there is clearly an unmet need for a therapeutic option, especially an oral one, that can mitigate harmful uncontrolled inflammation and dysfunctional immune responses during a SARS-CoV-2 infection. id="p-708" id="p-708" id="p-708" id="p-708" id="p-708" id="p-708" id="p-708" id="p-708" id="p-708" id="p-708" id="p-708"
[00708] Fortunately, over the past year there has been better understanding of the immunologic pathophysiology of COVID-19, which in later stages is driven primarily by host immune responses to the virus [16], In the spring of 2020, Applicants' team was the first to publish data linking the inflammasome / caspase-1 / pyroptosis axis to heightened pro-inflammatory IL-18 levels, lymphopenia and poor outcome in COVID-19 patients [6], Over the summer of 2020, a Brazilian study in over 100 patients expanded Applicants' findings, and also showed direct evidence of NLRP3 inflammasome activation and caspase-1 mediated pyroptosis in SARS-C0V-2-infected monocytes in vitro, as well as in blood and lung tissue of COVID-19 patients [17, 18], Inflammasome formation, as evidenced by expression of caspase-1 and NLRP3 in leukocytes and endothelial cells, was also found in the lungs of patients with fatal COVID-19 pneumonia [19, 20], Most recently, several studies further corroborated and expanded these findings by showing that SARS-CoV-2 infects monocytes and directly activates the inflammasome / caspase-1 / pyroptosis axis leading to pro-inflammatory cell death and cytokine release [21, 22], Importantly, it was further demonstrated that a caspase-1 specific inhibitor was effective in blocking pyroptotic cell death of SARS-C0V-2-infected monocytes and subsequent release of the pro-inflammatory cytokines IL-, IL-6, and TNF-a [21], In addition, from a mechanistic standpoint, it was recently shown that SARS-CoV-2 viroporin encoded by ORF3a activates the NLRP3 inflammasome and caspase-1 via potassium efflux [23], Moreover, key ORF3a amino acid residues required for 86 inflammasome activation were found to be conserved in virus isolates across continents, highlighting the universality of this inflammatory pathway [23], id="p-709" id="p-709" id="p-709" id="p-709" id="p-709" id="p-709" id="p-709" id="p-709" id="p-709" id="p-709" id="p-709"
[00709] Taken together, a growing body of evidence demonstrates that upstream SARS-CoV- 2-mediated inflammasome and caspase-1 activation leading to pyroptosis, trigger uncontrolled hyper-inflammation via cytokine release (IL-18, IL-1p, IL-6, and TNF-a) as well as immune dysfunction of monocytes and lymphocytes downstream [16, 24-28], Moreover, activation of the inflammasome / caspase-1 / pyroptosis axis could also explain COVID-19 related organ damage and tissue pathology of the heart, kidney, lungs, liver, pancreas and nervous systems, as it has been shown that SARS-C0V-2 also appears to cause pyroptosis in a variety of other cell types, including lung pneumocytes and endothelial cells in these organs [27-32], id="p-710" id="p-710" id="p-710" id="p-710" id="p-710" id="p-710" id="p-710" id="p-710" id="p-710" id="p-710" id="p-710"
[00710] Based on this growing body of evidence, this trial proposes that the orally-administered belnacasan, which following hydrolysi son contact with water is a highly specific caspase-1 inhibitor (also known as IL-1 converting enzyme) upstream of pyroptosis and pro-inflammatory cytokine release, is a much more targeted and potentially safer alternative to current generalized anti-inflammatory COVID-19 treatments such as corticosteroids, especially for comorbid patients with an already chronically-activated inflammasome [6, 25, 27, 28, 33-36] (FIG. 4). id="p-711" id="p-711" id="p-711" id="p-711" id="p-711" id="p-711" id="p-711" id="p-711" id="p-711" id="p-711" id="p-711"
[00711] Belnacasan (VX-765/RVT-201/MSR-001) id="p-712" id="p-712" id="p-712" id="p-712" id="p-712" id="p-712" id="p-712" id="p-712" id="p-712" id="p-712" id="p-712"
[00712] The drug substance has a molecular formula of C24N33CIN406 and has molecular weight of 509.0 and comes as a tablet preparation. It is hydrolyzed on contact with water to an active form and is a caspase-1 inhibitor (caspase-1 is also known as IL-1p converting enzyme).
Blocking this enzyme with belnacasan (VX-765/RVT-201/MSR-001) has been shown to prevent production of IL-1p, IL-18, and pyroptosis in healthy and disease states. The drug has been extensively developed originally by Vertex Pharma and more recently Roivant Sciences but currently has no FDA or IND approved usage for any indication. id="p-713" id="p-713" id="p-713" id="p-713" id="p-713" id="p-713" id="p-713" id="p-713" id="p-713" id="p-713" id="p-713"

[00714] Belnacasan (VX-765/RVT-201/MSR-001) has previously been studied in rodents and large animals including dogs and monkeys to doses of up to 2000mg/kg/day for toxicity studies in dogs. Dosing at these levels and in multi-dosing schedules have not shown any severe and particularly life-threatening side effects. In human trials, including for conditions such as seizure disorders, the drug has been trialed in increments of 300mg/dose on a TID or QID regimen up to 900mg QID for 13 weeks, in nearly 100 patients. 87 id="p-715" id="p-715" id="p-715" id="p-715" id="p-715" id="p-715" id="p-715" id="p-715" id="p-715" id="p-715" id="p-715"
[00715] Detailed pharmacokinetic studies from Vertex / Roivant are available for review. In brief, ex-vivo studies have demonstrated that Lipopolysaccharide stimulated IL- production is 50% suppressed by the active metabolite of belnacasan at a concentration of 0.8mcg/ml. This translated in to 50% suppression of IL-113 by single oral dose of 400mg while 80% suppression was achieved with doses of 800 and 1600mg. There was gradual but marked inhibition of IL-18 over 14 days in healthy controls as compared to placebo and 60% inhibition with 900mg TID as well as 1200mg TID and 1800mg TID during the duration of the study. For this study Applicants have therefore chosen Applicants' primary dose as 900mg TID in the absence of data on acute viral infection/ COVID-19. id="p-716" id="p-716" id="p-716" id="p-716" id="p-716" id="p-716" id="p-716" id="p-716" id="p-716" id="p-716" id="p-716"
[00716] The drug has previously been manufactured with appropriate due diligence in tablet form at 300mg/tablet (Data available from Roivant Sciences) and is manufactured by the same compounding pharmacy (Metrics), in the original format for immediate use in this trial. id="p-717" id="p-717" id="p-717" id="p-717" id="p-717" id="p-717" id="p-717" id="p-717" id="p-717" id="p-717" id="p-717"
[00717] For this trial Applicants treat for a maximum of 28 days. Applicants' rationale for this timeframe is that while there is an expectation that the illness lasts up to 12-15 days in those who recover without complication, others endure a longer duration, and some experience persistent, new onset or worsening disease related symptoms. A recent study from the Centers for Disease Control and Prevention (https://www.cdc.gov/mmwr/volumes/70/wr/mm7017e3.htm?s_cid=mm7017e3_w) found that among 3,171 non-hospitalized adult COVID-19 patients, 69% had one or more outpatient visits 28-180 days after the diagnosis. Two thirds had a visit for a new primary diagnosis, and approximately one third had a new specialist visit. Symptoms potentially related to COVID-19 were common new visit diagnoses. Visits for these symptoms decreased after 60 days but for some patients continued through 120-180 day. Furthermore, some individuals develop sequela that are likely related to post-viral immune dysregulation in the first few months albeit there is little known about this group. Though Applicants are unlikely to learn about the effect of the drug in this latter population Applicants do need to establish safety for a duration that includes the other groups mentioned above. id="p-718" id="p-718" id="p-718" id="p-718" id="p-718" id="p-718" id="p-718" id="p-718" id="p-718" id="p-718" id="p-718"

[00719] Based on files held by Vertex and Roivant Sciences, which contains evidence from animal and human studies, there is no indication that belnacasan (VX-765/RVT-201/MSR-001) 88 causes severe or life-threatening side effects. The only preclinical finding on toxicity studies was a reduction of the heart rate in dogs at 2000mg/kg/day, a dose that was estimated to be 10-25 times higher than the maximum in this study (900mg QID). In humans with epilepsy the drug has been used at dosages of 3600mg/day for up to 13 weeks. Adverse effects reported in humans were headache, dizziness, nausea and vomiting, abdominal discomfort and rash. Seizure was reported in more than one patient in one study on epilepsy. id="p-720" id="p-720" id="p-720" id="p-720" id="p-720" id="p-720" id="p-720" id="p-720" id="p-720" id="p-720" id="p-720"
[00720] In modern history there is been no greater health threat to life and livelihood than COVID-19, especially in the United States. While progress is being made to find treatments, there are potential drawbacks to all options. First, even with the prospect of vaccines being successful, there is a likelihood that patients with co-morbid conditions suffer a protracted illness at least; that it takes time for the vaccine and any needed boosters to reach critical mass in the population, especially in the face of vaccine hesitancy; and that vaccines might not always be effective, especially as new virus strands and variants continue to emerge and early data show that immunosuppressed patients may struggle to develop anti-bodies. Second, while the most frequently heralded therapeutic of remdesivir offers the potential for earlier clearance of the virus, the inflammatory cascade results in continued need for inpatient and especially intensive care in high-risk patients. Furthermore, as an IV drug, the treatment itself requires inpatient treatment and likely needs specific timing to be optimally effective. Third, the prospect of immunosuppression, for example with a broad therapy such as dexamethasone or other equivalent corticosteroid, affects the inflammatory cascade but any use beyond a few days carries risks and therefore disadvantages that Applicants believe come to light with greater use of the drug and scrutiny of outcomes going forward. Over the next 12 months it is reasonable to expect that a large part of the United States population undergoes vaccination with the majority of these individuals being afforded some immunity for what is yet an undetermined length of time. What is clear however is that this form of coronavirus is likely to be around for the foreseeable future and though fewer people are at risk for COVID-19, an effective treatment is necessary. While antiviral treatment may have an effect, it is clear from the pathophysiology that clearing virus may not be enough and such specific therapies to mitigate the individual's inflammatory response is important to reduce morbidity and mortality. Applicants believe that what is needed is an immunologically targeted medication that can be taken orally - and without the prospect of major immunosuppression in at-risk patients - 89 and that can even be taken for early treatment in high-risk patients. Based on the data presented here Applicants believe that belnacasan (VX-765/RVT-201/MSR-001) fulfils this role. id="p-721" id="p-721" id="p-721" id="p-721" id="p-721" id="p-721" id="p-721" id="p-721" id="p-721" id="p-721" id="p-721"

[00808] The drug in an oral form has been used in nearly one hundred patients without a history of major side effects. During the trial, it is therefore anticipated that no more than 2 subjects out of 24 have an adverse event of grade 4 or 5 that is at least possibly related to belnacasan (VX- 94 765/RVT-201/MSR-001). Should there be 3 or more subjects with an adverse event grade 4 or 5 that is at least possibly related to belnacasan (VX-765/RVT-201/MSR-001) in subjects receiving the IP, the study is put on an immediate clinical hold.

[00811] This is a phase 2 proof of concept randomized, double-blind, placebo-controlled trial with the purpose of assessing the safety, tolerability and treatment effect of the orally administered Caspase-1 inhibitor, belnacasan, for the treatment of patients with mild to moderate COVID-19. 24 subjects are given 900 mg TID of belnacasan and 24 subjects are given a placebo TID for 28 days, and assessments of safety, tolerability, and treatment effect are performed for up to 60 days. id="p-812" id="p-812" id="p-812" id="p-812" id="p-812" id="p-812" id="p-812" id="p-812" id="p-812" id="p-812" id="p-812"
[00812] At the screening / baseline / day 1 Visit, subjects provide informed consent and be screened for eligibility based on the Inclusion / Exclusion criteria Subjects also receive the first dose of study drug at this visit once study eligibility has been confirmed, and the second dose of study drug is taken approximately 8-12 hours after the first dose. Study drug is continued three times daily (morning, mid-day, and nighttime doses) through day 28. id="p-813" id="p-813" id="p-813" id="p-813" id="p-813" id="p-813" id="p-813" id="p-813" id="p-813" id="p-813" id="p-813"
[00813] The trial duration is approximately 60 days (8.5 weeks) for all subjects enrolled. As outlined in the Schedule of Events Table in Section 5.2, over the course of the study duration, all subjects use a diary to record IP intake as well as symptoms and activity levels with guidance to do so at the same time each day; assess physical parameters using a study-provided thermometer and pulse oximeter; be assessed at regular intervals via telemedical and in-person follow-up clinic visits; and give blood for laboratory tests. id="p-814" id="p-814" id="p-814" id="p-814" id="p-814" id="p-814" id="p-814" id="p-814" id="p-814" id="p-814" id="p-814"
[00814] Subjects are instructed to complete the diary at the same time each day, at a time that is consistently convenient for them. The Study Team conduct in-person visits with the subjects on days 7, 14, 21, and 28 and telephonic visits with subjects on days 1, 4, 10, 42, and 60. The Telemetry Care Team conducts telephonic visits daily through day 28. Subjects receive reminders to complete the diary via text message and / or email. Subjects who prematurely discontinue study drug for any reason are asked to have an Early Termination (ET) visit the day the last study drug 95 dose is administered; moreover, they are encouraged to stay enrolled so that further safety and outcome information can be collected and analyzed. id="p-815" id="p-815" id="p-815" id="p-815" id="p-815" id="p-815" id="p-815" id="p-815" id="p-815" id="p-815" id="p-815"
[00815] All data collected by the Study Team and Telemetry Care Team is entered into the EDC daily, for this trial OnCore is used. OnCore is a Clinical Trial Management System in which subject visits can be monitored as well as Case Report Forms developed. Subjects are asked to hand in their subject diary during visits on days 7, 14, 21, and 28. id="p-816" id="p-816" id="p-816" id="p-816" id="p-816" id="p-816" id="p-816" id="p-816" id="p-816" id="p-816" id="p-816"

[00817] All eligible subjects receive background standard of care, however there are certain prohibited medications subjects cannot be given while dosed with the IP as outlined in Exclusion Criteria. Background standard of care are commensurate with disease severity and aligned to standards at the time of the trial. At present, standard of care includes antiviral treatment with remdesivir, monoclonal antibodies against SARS-C0V-2, dexamethasone, supplemental oxygen, noninvasive and invasive ventilation, antibiotics, vasopressors and ECMO; but this may evolve over the coming months as new therapies or treatments come online. id="p-818" id="p-818" id="p-818" id="p-818" id="p-818" id="p-818" id="p-818" id="p-818" id="p-818" id="p-818" id="p-818"
[00818] Patients recruited to the study are not be asked to forgo background standard of care in any way. Recruitment is based on inclusion and exclusion criteria and include only individuals evaluated in an emergency room from designated institutions and triaged not to need in-hospital care. These individuals have the potential but not the likelihood for hospital admission with worsening COVID-19 disease progression. Current outpatient standard of care includes symptomatic treatment and this is not be altered to the point that analgesics and antipyretics are held. Patients whose CO VID-19 related illness deteriorates to the point that they need ambulatory medical care or hospitalization remain in the study and medical care as determined by managing physicians are not subverted in any manner as part of the study. Patient data collection as per study diary and study visits are maintained for the minimum 60 days and study drug is provided and monitored for compliance unless there is an indication for discontinuation of study drug, see section on drug discontinuation. id="p-819" id="p-819" id="p-819" id="p-819" id="p-819" id="p-819" id="p-819" id="p-819" id="p-819" id="p-819" id="p-819"

[00871] For enrolled subjects Applicants anticipate that the main reasons for discontinuation of therapy is either withdrawal of consent for continuation in the study or inability to tolerate the 100 study. Other instances may include patient death, inability to take the study drug from severity of illness or in-hospital complexity of illness. Subjective intolerance of the drug from minor side effects or alternatively cessation of COVID-19 related symptoms well ahead of the 28-day schedule may cause patients to want to discontinue the drug. With regards to drug toxicity itself, Applicants anticipate minor symptomatology from adverse effects, such as headache, dizziness, nausea and vomiting, abdominal discomfort and rash (see also 1.4) based on prior human trial experience with the study drug. Should any subject dosed on the study drug experience seizures, which was reported as an unrelated adverse event in an epilepsy trial, that individual would be subject to discontinuation out of an abundance of caution. Any emergent symptom that has no clear cause results in a hold on subsequent study drug dosing until protocol assessment by the Study Investigator. The reasons for discontinuation of study drug are documented clearly. In all cases study protocol monitoring continues for the entire 60 days of the protocol as long as the subject stays consented. id="p-872" id="p-872" id="p-872" id="p-872" id="p-872" id="p-872" id="p-872" id="p-872" id="p-872" id="p-872" id="p-872"
[00872] When a subject withdraws or is withdrawn before completing the study, the date and reason for withdrawal are to be documented. Subjects who withdraw or who are withdrawn prematurely are to attend an early termination, at which time they complete all assessments as outlined in the Schedule of Events (Table 1); moreover they are encouraged to stay enrolled so that further safety and outcome information can be collected and analyzed. id="p-873" id="p-873" id="p-873" id="p-873" id="p-873" id="p-873" id="p-873" id="p-873" id="p-873" id="p-873" id="p-873"

Acute kidney and/or hepatic injury are addressed in the following manner depending on whether at, (1) enrollment, (2) during the study period when drug is being administered in an ambulatory setting, (3) or during admission to hospital for COVID-19 related deterioration or other illness. id="p-904" id="p-904" id="p-904" id="p-904" id="p-904" id="p-904" id="p-904" id="p-904" id="p-904" id="p-904" id="p-904"
[00904] Potential participants in this study undergoes initial evaluation in the emergency room that includes background laboratory testing. If the testing indicates renal failure, GFR <30 or features of acute renal failure, most notably anuria, edema on examination in a previously healthy individual, the potential participant are not be enrolled as per the inclusion criteria or otherwise clarified with the nephrology consultant managing the patient. Similarly, potential participants shown to have evidence of elevated liver function tests (determined by ALT, AST, GGT, or ALP >2 x upper limit of normal, and total Bilirubin > upper limit of normal) is not be enrolled in the study. id="p-905" id="p-905" id="p-905" id="p-905" id="p-905" id="p-905" id="p-905" id="p-905" id="p-905" id="p-905" id="p-905"
[00905] Laboratory testing throughout the study period may, though unlikely, show an acute change in renal or liver testing to indicate acute organ-specific disease or involvement as a possible complication of COVID-19. In such a circumstance, subjects are directed to seek care from the respective hospital/specialist. In the case of acute liver injury with functional impairment, the IP is discontinued immediately after blood has been taken for future assessment of drug levels. In the case of subjects with elevated liver function tests suggestive of acute liver injury without functional impairment, IP is held to discern in the first instance the possibility of an adverse event and restarted in consultation with the managing hepatologist if it is determined to be CO VID-19 related hepatopathy. In the case of subjects with acute renal injury, IP is held to discern in the first instance the possibility of an adverse event and restarted in consultation with the managing nephrologist if 105 it is determined to be COVID-19 related nephropathy. DSMB guidelines for unblinding is followed in these cases as relevant. id="p-906" id="p-906" id="p-906" id="p-906" id="p-906" id="p-906" id="p-906" id="p-906" id="p-906" id="p-906" id="p-906"
[00906] Acute liver and kidney injury may be seen in the face of hospital admission in patients with worsening COVID-19, in which case the patients are managed similarly to number 2 above (also see discontinuation). id="p-907" id="p-907" id="p-907" id="p-907" id="p-907" id="p-907" id="p-907" id="p-907" id="p-907" id="p-907" id="p-907"

[00908] A treatment-emergent adverse event (TEAE) is defined as any event not present prior to the initiation of the treatments or any event already present that worsens in either intensity or frequency following the start of IP administration. id="p-909" id="p-909" id="p-909" id="p-909" id="p-909" id="p-909" id="p-909" id="p-909" id="p-909" id="p-909" id="p-909"
[00909] Adverse events are captured following the first dose of IP and could be related or unrelated to the study drug. A TEAE is defined as any AE that occurs after the subject takes the first dose of IP. id="p-910" id="p-910" id="p-910" id="p-910" id="p-910" id="p-910" id="p-910" id="p-910" id="p-910" id="p-910" id="p-910"

[00912] Clinical labs are performed locally at WHC or other MedStar clinical sites. Labs to be drawn during the study include serum chemistries, a hematology panel and an immune panel. A serum pregnancy test must be performed, and the result must be negative prior to the entry of women of child-bearing potential. id="p-913" id="p-913" id="p-913" id="p-913" id="p-913" id="p-913" id="p-913" id="p-913" id="p-913" id="p-913" id="p-913"
[00913] Clinical laboratory reports must be reviewed by a physician for out-of-range values within 12 hours of receipt. Out-of-range values are evaluated using the following notations: id="p-914" id="p-914" id="p-914" id="p-914" id="p-914" id="p-914" id="p-914" id="p-914" id="p-914" id="p-914" id="p-914"

[00918] By definition a lab value flagged as "CS" indicates an adverse event and are captured on the CRF. A laboratory test flagged "CS" should be repeated as soon as possible, then the Investigator should use his or her judgment as to whether the abnormal finding is sufficient reason to immediately withdraw the subject from the study. 106 id="p-919" id="p-919" id="p-919" id="p-919" id="p-919" id="p-919" id="p-919" id="p-919" id="p-919" id="p-919" id="p-919"
[00919] If a laboratory value is considered to be serious and life-threatening and at least possibly related to the study drug, the subject should be immediately discontinued from the study and appropriate therapy started.. id="p-920" id="p-920" id="p-920" id="p-920" id="p-920" id="p-920" id="p-920" id="p-920" id="p-920" id="p-920" id="p-920"

[00921] All adverse events, exacerbations of concomitant illnesses, or events known to be related to underlying disease processes or concomitant medications are to be recorded on the CRF throughout the study. If a pre-existing condition worsens during the study, the date on which the exacerbation began should be recorded. Onset dates for study treatment-related adverse events must be on or after the date of initial study treatment use. id="p-922" id="p-922" id="p-922" id="p-922" id="p-922" id="p-922" id="p-922" id="p-922" id="p-922" id="p-922" id="p-922"
[00922] Adverse event recording includes the date of onset, severity, duration, whether or not the study medication was discontinued because of the event, the treatment given, and the outcome.
The Investigator must also assess whether the event was related to the study medication, concurrent drug therapy, underlying disease, a combination of these factors, or if it is unknown. Subjects experiencing an adverse event should be carefully followed to determine outcome. id="p-923" id="p-923" id="p-923" id="p-923" id="p-923" id="p-923" id="p-923" id="p-923" id="p-923" id="p-923" id="p-923"
[00923] The Investigator use the NCI-CTCAE for adverse event monitoring, version 5.0 is applied in all instances. CTCAE version 4.03 may also be used especially when assessing laboratory tests given the complexity in applying version 5.0 in all instances, see www. lexj ansen.com/phuse-us/2020/dh/DH 16. pdf id="p-924" id="p-924" id="p-924" id="p-924" id="p-924" id="p-924" id="p-924" id="p-924" id="p-924" id="p-924" id="p-924"

[00946] Life-threatening: An event which a subject was at risk of death at the time of event.
There is a distinction between the severity and the seriousness of an adverse event. Severity is a measurement of intensity, thus a severe reaction is not necessarily a serious adverse event. For 108 example, a headache may be severe in intensity, but would not be serious unless it met one of the criteria for serious adverse events listed previously. id="p-947" id="p-947" id="p-947" id="p-947" id="p-947" id="p-947" id="p-947" id="p-947" id="p-947" id="p-947" id="p-947"

[00948] Adverse events (AEs) and serious adverse events (SAEs) is collected from the time the first dose of IP is administered until 28 days after the last dose of IP. Medical occurrences that began prior to the start of study treatment, but after obtaining informed consent is captured as Medical History/Current Medical Conditions on the CRF. The Investigator or site staff is responsible for the identification and documentation of events meeting the criteria and definition of an adverse event or serious adverse event, as provided in the study protocol. SAEs assessed as related to study participation (e.g., dosing, protocol mandated procedures, invasive tests, or change in existing therapy) or related to a concomitant medication is captured once the subject has taken the first dose of study medication. id="p-949" id="p-949" id="p-949" id="p-949" id="p-949" id="p-949" id="p-949" id="p-949" id="p-949" id="p-949" id="p-949"
[00949] In the event of an AE or SAE, it is the responsibility of the Investigator to review all documentation (e.g., hospital progress notes, laboratory, and diagnostics reports) relative to the event and attempt to establish a diagnosis of the event based on signs, symptoms, and other clinical information. Once the Investigator becomes aware that an SAE has occurred, they are' to report the information to MedStar Health within 24 hours and provide an assessment of causality. id="p-950" id="p-950" id="p-950" id="p-950" id="p-950" id="p-950" id="p-950" id="p-950" id="p-950" id="p-950" id="p-950"

[00951] The Sponsor reports all serious adverse events to regulatory agencies as required. In addition to the serious adverse events described previously, other events that in the Investigator's opinion suggest a significant hazard, contraindication, or precaution should be considered serious.
This includes, but is not limited to, blood dyscrasias, endocrine disturbances, hemorrhage from any site, or severe skin disorder. Additional examples are intensive treatment for allergic bronchospasm, blood dyscrasias or convulsions. id="p-952" id="p-952" id="p-952" id="p-952" id="p-952" id="p-952" id="p-952" id="p-952" id="p-952" id="p-952" id="p-952"
[00952] Subjects who experience an SAE must be given appropriate examinations and treatment. The Investigator must provide written information to the Sponsor as soon as possible. id="p-953" id="p-953" id="p-953" id="p-953" id="p-953" id="p-953" id="p-953" id="p-953" id="p-953" id="p-953" id="p-953"

[00956] In medical emergencies, the Investigator should use medical judgment and remove the subject from immediate hazard. As soon as possible after removing the subject from hazard, the Investigator must contact MedStar Health by telephone to permit a decision as to whether the subject may continue in the study. The IRB should also be notified as to the type of emergency and the course of action. The CRT for the subject must capture the departure from the protocol and state the reason. id="p-957" id="p-957" id="p-957" id="p-957" id="p-957" id="p-957" id="p-957" id="p-957" id="p-957" id="p-957" id="p-957"

[00958] A Data Safety and Monitoring Board (DSMB) is established to monitor the safety of the subjects during the study. The DSMB includes members who are independent of this study and its Sponsor Team, and with relevant clinical expertise, including a good understanding of the safety of medications for respiratory illnesses. These members may include one or more of the following- a statistician, an infectious disease specialist and/or a pulmonologist. The methodology and the operating procedures for the safety reviews are developed by the infectious disease specialist and/or pulmonologist in collaboration with the Investigator and are documented in the DSMB Charter. They review all SAEs and determine whether the study can proceed or whether protocol modifications are required. id="p-959" id="p-959" id="p-959" id="p-959" id="p-959" id="p-959" id="p-959" id="p-959" id="p-959" id="p-959" id="p-959"

[00976] All safety & tolerability analyses are performed on the Safety Population. The safety data ise presented in individual listings and summary tables. id="p-977" id="p-977" id="p-977" id="p-977" id="p-977" id="p-977" id="p-977" id="p-977" id="p-977" id="p-977" id="p-977"
[00977] Overall safety is assessed by the number of belnacasan VX-765/RVT-201/MSR-001 dosed subjects experiencing a grade 4 or 5 SAE during the trial. Of 24 subjects enrolled in the belnacasan group, 3 or more developing a grade 4 or 5 SAE potentially related to belnacasan would be considered unlikely due to chance. id="p-978" id="p-978" id="p-978" id="p-978" id="p-978" id="p-978" id="p-978" id="p-978" id="p-978" id="p-978" id="p-978"
[00978] Therefore, belnacasan is determined safe if no more than 2 subjects develop a grade 4 or 5 SAE in the belnacasan group potentially related to belnacasan. If 3 or more subjects in the belnacasan group develop SAEs potentially related to belnacasan during the trial, belnacasan is considered not safe, and the trial stopped or placed on clinical hold as noted. id="p-979" id="p-979" id="p-979" id="p-979" id="p-979" id="p-979" id="p-979" id="p-979" id="p-979" id="p-979" id="p-979"

[00980] Primary endpoints of adverse and serious adverse events (AE/SAE) is assessed by Poisson regression for count data. Events are counted out to 60 days from randomization to belnacasan or placebo groups. Because some subjects may be followed for less than 60 days, subject follow-up time are included in the Poisson regression as the exposure time variable. If counts are not Poisson-distributed, either over- or under-dispersed, negative binomial regression analyze AE/SAE events with appropriate adjustment for over/under dispersion. Comparison of belnacasan vs. placebo is expressed as the incidence rate ratio (IRR). id="p-981" id="p-981" id="p-981" id="p-981" id="p-981" id="p-981" id="p-981" id="p-981" id="p-981" id="p-981" id="p-981"

[00982] AEs are coded according to the latest version of the Medical Dictionary for Regulatory Activities (MedDRA). The intensity/severity of AEs is graded according to NCI CTCAE. id="p-983" id="p-983" id="p-983" id="p-983" id="p-983" id="p-983" id="p-983" id="p-983" id="p-983" id="p-983" id="p-983"
[00983] TEAEs, AEs leading to study treatment discontinuation, AEs leading to dose interruption, AEs related to study medication, SAEs, and AEs leading to death are summarized by system organ class, preferred term, and study period. A summary of AEs that are CTCAE Grade 3 or higher, as well as the most frequent preferred terms, are provided. id="p-984" id="p-984" id="p-984" id="p-984" id="p-984" id="p-984" id="p-984" id="p-984" id="p-984" id="p-984" id="p-984"
[00984] If a subject experiences the same adverse events multiple times within a period, then the event is counted only once within the period and by greatest severity. id="p-985" id="p-985" id="p-985" id="p-985" id="p-985" id="p-985" id="p-985" id="p-985" id="p-985" id="p-985" id="p-985"

[00996] Event counts over 60 days are analyzed by Poisson regression as described above in 8.4. Time to events are analyzed by Cox regression. Differences between belnacasan and placebo with respect to change in continuous endpoints are assessed by mixed effects models for continuous repeated measures data and mixed effects logistic models for repeated categorical variables. Endpoint proportions of belnacasan and placebo groups are assessed by contingency table analysis (chi-square). id="p-997" id="p-997" id="p-997" id="p-997" id="p-997" id="p-997" id="p-997" id="p-997" id="p-997" id="p-997" id="p-997"

[00998] Although every effort is made to obtain complete data, missing values likely occur when data are collected longitudinally. Patterns of missingness over time as well missingness with respect to demographic and clinical variables are assessed. For Poisson and Cox regression analyses, all data can be used up to subject dropout time. id="p-999" id="p-999" id="p-999" id="p-999" id="p-999" id="p-999" id="p-999" id="p-999" id="p-999" id="p-999" id="p-999"

[001000] A total of 48 subjects are randomized, 24 to belnacasan (VX-765/RVT-201/MSR-001) 900 mg TID and 24 to placebo. As this is a proof-of-concept study, it is likely not powered to 113 detect belnacasan - placebo differences that are clinically meaningful. For example, the observed difference in primary endpoint rate ratios would need to be over 60% to achieve 80% power with an alpha error rate of 5% for 24 subjects in each group. This study provides an estimate of the belnacasan effect size to inform a larger trial where a more clinically meaningful difference can be detected. id="p-1001" id="p-1001" id="p-1001" id="p-1001" id="p-1001" id="p-1001" id="p-1001" id="p-1001" id="p-1001" id="p-1001" id="p-1001"
